`UNITED STATES PATENT OFFICE.

T. P. THORPE, OF NEW YORK, N. Y.

ExERolsINc-MACHINE.

Specification forming part of Letters Patent No. 47,999, dated May 30,1865.

.To all whom, it may concern,.-

Be it known that I, T. P. THORPE, of the city and county of New York,and in the State of New York, have invented a new and luseful article ofhousehold furniture for the purpose of exercise and amusement ofchildrensaid article I term or designate a Teeter- Totter 7 forperpendicular scupping or teetering; and I do hereby declare that thefollow ing is a full and exact description thereof, reference being hadto the accompanying drawing, and to the letters of reference markedthereon.

The nature of my invention consists in producing or manufacturing a veryuseful household article, as it acts as a great assistant in amusing orquieting babies or older children.

To enable others skilled in the art to make and use my invention, I willproceed to .describe its construction and operation.

A A are cross-bars,which point in four different directions, and are abase, and also a part of the said article of invention.

Bis an upright or post, which stands in the center of said cross-bars,and through which rests what maybe termed a walking-beam, (marked C.) Oneither end of said walkingbeam is an armed seat, each marked D, having amovable front with straps marked E. Over the center of said walking-beamC, and running through the top of the post marked B, is a shaft markedN. and on the end of said shaft is a crank marked M, said crank having ahandle marked O, said handle being amovable screw. Attached to saidshatN are two separate springs, (marked P P,) said springs bending orwinding around (and attached to) said shaft Nin diiferent directions,their outer ends being fastened to rods marked R R, said rods beingattached to the walking-beam C in front of seats D D. Immediately on thetop of the post B is aladys sewing or work basket,

(marked S.)

In operating the teeter-totter, either one or two children 'can manageit. The child is placed on one of the seats D D, with `its feet hangingover the front part ofthe seat D. The movable front of said seat (markedE) is then closed up and fastened, so that it encircles the chest,reaching under the arms, the straps being made fast to the inner part ofthe back of the seat, when the child is perfectly secure and safe. Ithen take hold of the handle marked O and unscrew it, and move the crankmarked M either to or from the child, by which means I regulate thepower of the springs P' P, and continue to do so until the childs feetjust touch the floor, when the handle marked O is screwed into one ofthe holes made for it, near the top of the post marked B. The child thenkicks or pushes with its feet against the floor, which causes it toascend up by the power of one ofthe springs P P, its own weight alwaysagain bringing it to the floor; and so it continues scupping crteetering to its own amusement.

Vhen there are two children-one on either seat-it is always necessary toregulate the power of the springs P P in the manner as above described,so that the feet of one of them just touches the door, when the scuppingor teetering motion, as above, can be given to both of them.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The springs PP, or their equivalent, combined with the walking-beammarked C, and

the shaft N, together with the post B, for the purpose herein described.

2. The device as a new article of manufacture, as above combined anddescribed, for the purpose herein intended and described.

T. P. THORPE.
